Corporate departments outside of the IT department, globally, are forecast to spend $609bn in 2017:

A new update to the Worldwide Semiannual IT Spending Guide: Line of Business from the International Data Corporation (IDC) forecasts worldwide corporate IT spending funded by non-IT business units will reach $609 billion in 2017, an increase of 5.9% over 2016. The Spending Guide, which quantifies the purchasing power of line of business (LoB) technology buyers by providing a detailed examination of where the funding for a variety of IT purchases originates, also forecasts LoB spending to achieve a compound annual growth rate (CAGR) of 5.9% over the 2015-2020 forecast period. In comparison, technology spending by IT buyers is forecast to have a five-year CAGR of 2.3%. By 2020, IDC expects LoB technology spending to be nearly equal to that of the IT organization.

Meanwhile, all in, global IT spend was estimated at $2.4tn in 2016, but that includes telco and consumer tech. And, this demographic breakdown for enterprise IT spend:

In terms of company size, more than 45% of all IT spending worldwide will come from very large businesses (more than 1,000 employees) while the small office category (the 70-plus million small businesses with 1-9 employees) will provide roughly one quarter of all IT spending throughout the forecast period. Medium (100-499 employees) and large (500-999 employees) business will see the fastest growth in IT spending, each with a CAGR of 4.4%.

Worldwide revenues for information technology (IT) products and services are forecast to reach nearly $2.4 trillion in 2017, an increase of 3.5% over 2016. In a newly published update to the Worldwide Semiannual IT Spending Guide: Industry and Company Size , International Data Corporation (IDC) estimates that global IT spending will grow to nearly $2.65 trillion in 2020. This represents a compound annual growth rate (CAGR) of 3.3% for the 2015-2020 forecast period.

For the year, Gartner estimated shipments at 269.717 million, down 6.2 per cent year-on-year, with each of the major manufacturers except Dell reporting falling sales.

Gartner says high-end PCs are doing well, but of course, are a smaller market:

There have been innovative form factors, like 2-in-1s and thin and light notebooks, as well as technology improvements, such as longer battery life. This high end of the market has grown fast, led by engaged PC users who put high priority on PCs. However, the market driven by PC enthusiasts is not big enough to drive overall market growth.

There may less volume, but it’d be nice to know how that effects profits in the notoriously slim margin PC business.

“In 2015, the worldwide application performance management software market grew an estimated 12.1% over that in 2014, in large part because of increased demand for a new generation of solutions designed to support DevOps and multicloud infrastructure initiatives,” explains Mary Johnston Turner, research vice president, Enterprise System Management Software. “This new generation of APM solutions is easier to implement, supports more sophisticated analytics, and is less expensive than earlier offerings. As a result, APM is providing value to a much wider range of developers and IT operations teams that need constant, current visibility into end-to-end application performance and end-user experience.”

Instead, it has created a great divide, said Pucciarelli. “This siloed, divided approach brings frustration, disappointment and failure in multiple ways.” For one thing, it doesn’t support healthy team spirit, he said, and the innovation side tends to operate fast to deliver business solutions without the accountability around reliability, quality and security that is expected from the traditional IT side. “It leads to redundancy and inefficiency.”
